2018 Volkswagen Transporter 2.0L Diesel · MJ18 MDJ

A lingering engine‑management fault dominates the latest MOT picture – the 8 July 2026 test recorded a failure for an inoperative or malfunction‑indicating MIL (Malfunction Indicator Lamp), meaning the electronic control system signalled a problem that prevented a pass. The same test also listed a rear fuel‑tank strap that is slightly loose and a nearside rear anti‑roll‑bar linkage pin or bush showing wear, both noted as advisories. Apart from this isolated failure, the vehicle has otherwise cleared its MOTs since 2021, with only advisory items appearing in earlier years, indicating a generally stable road‑worthiness record punctuated by a single electronic fault that now requires attention. At 148,269 miles the van averages roughly 18,500 miles per annum, a relatively high utilisation for a 2018 model. The mileage progression is consistent across the eight‑year span, with no large gaps between tests, suggesting the odometer reflects genuine use rather than periods of storage. Such mileage accelerates wear on consumables – brake linings, tyre tread, suspension bushings and engine components – and raises the probability of age‑related corrosion, especially on parts already flagged as corroded in the 2024 MOT. The engine‑MIL failure should be diagnosed with a scan tool to retrieve any stored fault codes; common culprits include oxygen‑sensor faults, exhaust‑gas recirculation issues or injector problems. On a test drive, listen for irregular idling, hesitation under acceleration, or a loss of power, and confirm that the check‑engine light remains illuminated after a cold start. Given the vehicle’s mileage, also inspect the condition of the coolant and oil levels, and watch for any unusual exhaust smoke that could indicate a deeper engine fault. The rear fuel‑tank strap looseness warrants a visual inspection for signs of fuel leakage, especially after a short drive; a dripping or damp spot under the rear of the van would confirm a seal problem. The nearside rear anti‑roll‑bar bush wear should be checked by applying pressure to the rear suspension and feeling for excessive play or clunking over bumps, which could affect handling stability. Corroded rear discs and coil springs noted in 2024 may translate into reduced braking efficiency and a harsher ride – feel the brake pedal for pulsation and listen for metal‑on‑metal noise when braking. Thin front brake linings recorded in 2022 should be verified by measuring pad thickness; a thin pad will produce a higher pedal travel and a squealing tone. Finally, the frayed off‑side front seat‑belt webbing and the non‑functioning nearside rear position lamp are safety‑related items that should be replaced or repaired before the next MOT.
